General repair guidelines for TV LCD LED
If the UE32ES5530W TV does not turn on, does not make any sounds when it is turned on, and also no indicators on the front panel light or blink, there is a high probability of a malfunction in the power supply module. In some cases, there may be a malfunction only in standby power. When diagnosing and repairing the power supply, after replacing the swollen capacitors of the filters of the secondary rectifiers (if any), you must first check the mains fuse. When it is broken, the power elements of transistors and rectifier bridge diodes should be checked for avalanche (thermal) breakdown.
Mos-Fet keys used in switching power supplies (SMPS) rarely fail for no reason to look for when checking other circuit elements. Often the breakdown is caused by malfunctions of electrolytic capacitors or semiconductor elements in the primary circuit, or by a break in resistors in the stabilization circuits. The SSC2S110 PWM controller chip can also cause a breakdown of the power switch of the converter.
The LED driver for powering the backlight LEDs is located on the Power Supply (PSU) board and is a step-up voltage converter with current stabilization in the load.
Sometimes the SAMSUNG UE32ES5530W TV does not have an image, but there is sound, or the image appears and immediately disappears. In this case, there is a possibility of a malfunction of the LED driver, or a break in the LED circuit is possible.
In the event of breaks in the LED circuit, a complete disassembly of the panel is required, all LEDs are checked for breakage or breakdown, as well as the reliability of the connections in the connectors and rations of the terminals.
It should be remembered that it is not possible to determine the break in the LED lines without disassembling the panels with a tester or multimeter without an additional device, for example, a current source. To open all PN junctions connected in series, you may need a voltage of several tens of volts.
The motherboard BN41-01812A must be checked if there is no reaction to the remote control and function buttons, the standby indicator blinks or lights up continuously. In such cases, if the converters or power regulators of the microcircuit are working, a software update may be necessary.
When repairing an MB board, you must check its components WT61P805 K4B2G1646C-HCK0 NTP-7412S. Defective items should be replaced. If BGA chips are installed, their malfunction is usually localized by heating.
If you suspect a malfunction of the DT0D40FVL084AA BN40-00232A tuner, first of all, you need to make sure the software is correct, as well as the presence of the necessary voltage levels at the corresponding terminals of the tuner. Data exchange on the I2C bus with the processor can be observed using an oscilloscope.
Remember! Attempts to self-repair by users of the SAMSUNG UE32ES5530W TV without the appropriate qualifications and necessary experience can lead to serious negative consequences!

Main features of the SAMSUNG UE32ES5530W device:
Installed matrix (LED panel) LE320BGM-C1.
The matrix control uses the Timing Controller (T-CON) V320HJ2-CPE2 ;.
To power the backlight LEDs, a converter is used, combined with a power supply, controlled by the SLC2012M PWM controller. As power elements of the LED driver, keys of the MDD5N40 type are used.
The necessary supply voltages for all nodes of the SAMSUNG UE32ES5530W TV are generated by the BN44-00501A power module or its analogs using SSC2S110 microcircuits and 13NM60N type power switches.
